The general trend of cable design and costs are reviewed and consideration is given to capital charges, I2R loss, sheath loss, dielectric loss and reactive compensation. It is shown that for the higher voltages the costs of the dielectric loss and reactive compensation are more important than those of the I2R loss. These fixed costs and also the charging current and impulse strength are dependent on the value of the designed maximum stress on the dielectric, and it is shown that the value of this stress must not be increased without consideration of all its etfects. The total cost of cable installations is reviewed and the economic voltages for various loads derived. The total costs of cable installations are analysed and examples given of the increase in cost of energy due to transmission. The author appreciates that the choice of voltage and cable size is not governed solely by considerations of the cable, since the cost of terminal equipment, short-circuit duty and voltage drop are sometimes the determining factors, These considerations are, however, outside the scope of this paper.

The paper deals with the design and production of small generating plant for the Services, and in particular the Army, up to 1944. After giving an idea of the size of the demand and active service requirements it proceeds to deal with the special requirements of various powerconsuming apparatus. Descriptions, accompanied by illustrations, of the more interesting sets follow. The difficulties encountered in production and design are described, and the attributes of American sets are touched upon. In conclusion, the author emphasizes that many of the difficulties could have been avoided by intelligent anticipation during the years preceding the war, and that the post-war organization is likely to be superior in this respect. Plant used for general power production in camps, etc., does not come within the scope of the paper.

The Irish Electricity Supply Board, operating since 1929, generates power in hydro and fuel stations and delivers it to the consumers' terminals. The paper deals with the more important or interesting features of the system and of its operation, having particular regard to possible differences in practice compared with Great Britain. Sufficient particulars of the plant are given to enable the subsequent information on operation, performance and maintenance to be appreciated. Arcsuppression plant has been extensively used, and experience has been obtained of a wide variety of types of transformer and of switch and control gear. Overhead lines and underground cables are dealt with and some fault statistics are given.
